Limitations regarding reserve_policy and path selection algorithms in AIX

Follow

AIX supports several SCSI reservation policies and path selection algorithms.

Our interoperability tests found the following limitations which are not covered in the official documentation for AIX on the IBM website:

  • attribute "algorithm=shortest_queue" is only available on AIX 6.1TL9 or AIX 7.1TL3 or later
  • attribute "reserve_policy=single_path" is only available if "algorithm=fail_over"
  • attribute "reserve_policy=PR_exclusive" or "reserve_polciy=PR_shared" is only available if "PR_key_value=1"
